Abstract
An information processing system includes a plurality of bus devices coupled to at least one storage device via a bus. A first device (the "requestor") on a bus issues a request to obtain data and coherency information and monitors for the coherency information during a designated coherency response interval. A second device (the "respondant") sends a first signal during the designated coherency response interval indicating that the coherency information will be returned during a second interval, and sends a second signal providing the coherency information to the requestor during the second interval.
